Ingabe umbiko wokuhlola isifaki se-VPN umayelana nefayela lakho?
Qhathanisa i-hashi ehloliwe, ilebula yinjini kanye nesikhathi sombiko nesifaki osiphethe. Inani lokutholakala lodwa alikwazi ukukhulula noma ukulahla ukwakhiwa kwe-VPN.
Umbiko wokuhlola ohlanganisiwe uchaza into eyodwa eyathunyelwa ngesikhathi esisodwa, hhayi umndeni womkhiqizo. Ngaphambi kokuba ukutholakala kushintshe noma isiphi isinqumo, qinisekisa ukuthi i-hashi esembikweni ihambisana nefayela elikudiski lakho nokuthi injini elebulwe, usuku kanye nenguqulo kuhambisana nale nto. Uma kwephulwa noma yisiphi kwalawa makhempasi amathathu, inani eliseduze kwegama lefayela alikabi ubufakazi mayelana nokwakhiwa kwakho. Izinyathelo ezingezansi zihamba ngokulandelana, futhi ngasinye singamisa ukubuyekezwa.
Yima lapho kungafanisani khona okokuqala esikhundleni sokuphikisana ngamaphuzu.
Qala ngefayela, hhayi ngamaphuzu
Bhala i-SHA-256 yale nto ngaphambi kokuba okunye kuyithinte. Yikopishe kusuka kufolda yokulanda hhayi kufolda eyabiwe okungenzeka ukuthi isivele inekhophi epakishwe kabusha, futhi bhala umucu wenguqulo kanye nomshicileli okuboniswa ezimfanelweni zefayela. Umbiko obhekiswe kusifaki sasekukhululweni okubili okudlule awusho lutho mayelana nokwakhiwa abasebenzisi bakho abazokufaka namuhla, ngisho noma igama lomkhiqizo, isithonjana kanye nomthengisi kuhambisana. Amagama akhethwa yilowo opakisha ifayela; ama-hashi awakhethwa kanjalo.
Gcina leyo hashi kanye nesixhumanisi sombiko ukuze labo ababili babuyekezwe kamuva.
Funda ukutholakala, bese kuba yinjini
Inombolo yesihloko ibala izinjini ezihambisana nokuthile, futhi lokho kuhambisana akulingani. Isiginesha enegama ichaza umndeni noma ukuziphatha injini ethi iyakwazi ukukubona; ilebula ye-heuristic noma yedumela ichaza ukusola komthetho, okubuthakathaka futhi okulula ukushintsha phakathi kwezibuyekezo zezincazelo. Ikholomu yinjini ikutshela ukuthi imuphi umthengisi ongumnikazi wokutholakele ngakho-ke imuphi umthengisi ongakubuyekeza noma akulungise. Izinjini ezimbili ezimaka ifayela elilodwa akubona ubufakazi obuphindwe kabili uma zombili zikopishe isethi efanayo yeziginesha.
Hlola nesigxivizo sesikhathi sokuhlaziya. Isinqumo singashintsha lapho iziginesha zibuyekezwa noma lapho umthengisi ehlaziya isampuli kabusha.
Qhathanisa umbiko nale nto onawo
Bala i-hashi endaweni yakho kule pletafomu ozosabalalisa kuyo, bese uyiqhathanisa nombiko unobumba ngonobumba. Le mikhiqizo ikhipha isifinyezo ngaphandle kokusebenzisa isifaki.
# Windows certutil -hashfile .\vpn-client-setup.exe SHA256 Get-FileHash .\vpn-client-setup.exe -Algorithm SHA256 # macOS shasum -a 256 ./VPNClient.pkg # Debian/Ubuntu sha256sum ./vpn-client_amd64.deb
Isifinyezo esihambisanayo sihlanganisa umbiko nalolo chungechunge lwamabhayithi futhi akukho okunye. Uma izifinyezo zihluka, umbiko ungowefayela elihlukile futhi ukubuyekezwa kuqala kabusha emthonjeni wokulanda.
Lapho izifinyezo zihambisana, funda ukutholakele ngokugcwele: injini, ilebula, inguqulo, usuku lokubonwa okokuqala kanye nanoma yimuphi umbhalo mayelana nokuthi ifayela lisayiniwe noma lipakishiwe. Bese uhlola isihloko somsayini kule nto uqobo, ngoba isiginesha evumelekile yengeza ubunikazi bomshicileli ngaphandle kokuxazulula ukuziphatha.
Thumela umbuzo kumnikazi ofanele
Umthengisi wale njini kuphela ongakwazi ukubuyekeza ukutholakala kwayo, ngakho isimangalo sokungalungile siya esiteshini sokubuyekeza salowo mthengisi kanye ne-hashi, isixhumanisi esihlala njalo sombiko kanye nencazelo yefayela. Umshicileli wesofthiwe angahlinzeka ngokwakhiwa okumsulwa noma incazelo kodwa akakwazi ukususa ilebula lenye inkampani. Ukuthumela kuqala kumshicileli kuvame ukwengeza iviki futhi kungabi nalwazi.
Gcina inqubomgomo yokuvikela iphuzu lokugcina injalo ngenkathi ukubuyekezwa kuqhubeka. Ukucisha isihloli noma ukwengeza ukukhishwa kwefolda okubanzi kuxazulula isixwayiso ngaphandle kokuphendula ukuthi yiliphi ifayela elahlolwa, futhi kufihla ukwenzeka okulandelayo kwesimo esifanayo.
Yabelana ngokuncane okudingekayo ukukhomba isifaki somphakathi: i-hashi, igama lefayela, inguqulo kanye nesixhumanisi sombiko. Iphrofayela yeklayenti, ukhiye wangasese noma isithombe esigcwele sememori akudingekile kulokho, futhi ukulayisha okukodwa kwalokho kuguqula umbuzo wesofthiwe ube yisigameko sokuphatha idatha.
